7mm scale/0 gauge Conductor Rail
I
deal for modelling LSWR-SR-BR-Metropolitan-London Transport-Mersey Rail-NER etc. 3rd & 4th Rail

Since introducing our popular 7mm scale flatbottom rail sections, we have received frequent requests from customers wishing to model live rail electrified lines, all asking for accurate 7mm scale conductor rail. This posed something of a problem because, historically, 3rd & 4th rail electrified systems have used a number of differing conductor rail sections, and it simply wasn't practical to do more than one size. After much deliberation and careful design, we have produced a section which represents as closely as possible the most commonly used rails of 100lb, 106lb and 150lb/yard. Most importantly, we have been able to accurately replicate the distinctive wide head and foot forms which are such a striking visual feature of this type of rail.

7mm scale conductor rail
 

Head width: 1.92mm (0.075")
Foot width:  3.20mm (0.125")
Rail height:  2.77mm (0.110")

C110/7CR - to represent, in 7mm scale, prototype 100-150lb/yard conductor rail - £30.00 per 25ft

Each pack of 25 feet contains 10 x 30" (762mm) lengths in high-Ni nickel silver.


A range of insulators (6 types) and fishplates will be available shortly. It was hoped these would become available at the same time as the rail, but a minor production glitch has put paid to that. Watch this space...

Although a little more expensive than traditional ordinary 'yellow' nickel silver, our high-Ni provides a far more realistic, steel-like appearance. Mail orders are sent packed in a specially made thick-wall protective tube. Please note that when sending rail by post there is a separately applied postage and packing charge: a minimum of £6.50 in the UK, and subject to weight thereafter. This is normally sufficient to cover the cost of sending at least a couple of packs of rail - if ordering a greater quantity, or from overseas, please ask for a postage quote.

Price Rises

The prices we charge for our rails have remained fixed for over three years. During that time, the ex-factory cost to us has very nearly doubled.
Regrettably, a fairly substantial increase in our prices is now unavoidable - details in the panel to the right.

Karlgarin Rail - Our own range of accurately scaled and profiled flatbottom rails made specifically for 7mm scale/0 gauge.

We have invested heavily in new tooling and can now offer three sizes of accurately profiled 7mm scale flatbottom rails, produced exclusively to our own exacting specification. Though primarily intended for 1:43 7mm scale use, they are also eminently suitable for 1:48 O scale and 1:32 scale/Gauge 1 applications. Perfect for modelling both standard and narrow gauge prototypes - no more undersized 'fence wire' rails of 00/H0 origin!

Enlarged photograph showing all three sizes - amongst the detail differences, note that the 82/7 has the correct flat top as commonly found on the prototype of this lighter weight of rail.

Code   82/7 - to represent, in 7mm scale, prototype 40-45lb/yard rails - £13.50 per 25ft
Code 100/7 - to represent, in 7mm scale, prototype 60-70lb/yard rails - £15.50 per 25ft
  Code 125/7 - to represent, in 7mm scale, prototype 80-100lb/yard rails
- £19.50 per 25ft


In 1:32 scale Gauge 1, these sizes are approximately equivalent to 20lb, 35lb and 50lb/yard rails respectively.

Metric equivalents in 7mm scale:
Code   82/7 - 20-21kg/m rail
Code 100/7 - 27-31kg/m rail
Code 125/7 - 41-49kg/m rail

All our rail is made from top quality high-Ni nickel silver. Although a little more expensive than traditional ordinary 'yellow' nickel silver, our high-Ni provides a far more realistic, steel-like appearance. One pack of 25 feet contains 10 x 30" (762mm) lengths.

Why 30" lengths? Years of trackbuilding experience indicates that there will be less waste from 'short' left-over pieces; it is also easier and safer to handle, and cheaper to post.

Mail orders are sent packed in a specially made thick-wall protective tube. Please note that when sending rail by post there is a separately applied postage and packing charge: a minimum of £6.50 in the UK, and subject to weight thereafter. This is normally sufficient to cover the cost of sending at least a couple of packs of rail - if ordering a greater quantity, or from overseas, please ask for a postage quote.

DELRIN® CHAIN DRIVE SYSTEM
Due to a problem at the manufacturers, supplies of Delrin® Drive components have been unobtainable for quite some time. Happily, the situation has improved, and we now have good stocks.

2 DOORS DOWN GE type Box Cab loco kit. A surprise new addition to this interesting 0 gauge (1:48 scale) range of little 'Critters'.
In addition, another batch of the popular little GE 25 Tonner has been produced. Both kits are in stock now, along with wheels, motors and gears to suit. As can be seen from the photographs, these kits make up into delightful models.

A full set of the instructions for the 2 DOORS DOWN GE 70 tonner added. We have put these up to allow anyone interested in this new range to see just what they are getting for their money.
A number of customers have been very complimentary about the way these kits go together.

0 GAUGE AMERICAN DIESELS by 2 DOORS DOWN: Following the review published in the November 2003 Continental Modeller, here is a brief resume to whet your appetites. More details and photographs of built kits can be found by clicking the link above.

First release will be a 25 ton 4-wheel switcher based on the GE prototype first introduced in the 1940's.
Next up is the EMD 300hp centre-cab 4-wheel switcher.
Third of the trio is the GE 70 ton Bo-Bo, available in both early and later versions.

The kits are etched brass, with detail castings in whitemetal. They are designed to be motorised using Slater's wheels, Mashima motors, Romford Gears and Delrin chain and sprocket drive, all of which we can supply from stock. Pickups and couplings are not supplied. All kits have been designed to accept Kadee™ auto-couplings.

'RooKits 40-1 gearset

 


Preparing for the reintroduction of our range of IMPETUS small locomotive kits, it has become painfully apparent that supplies of some of the bought-in components required to complete the model were either rather uncertain, of variable quality, too expensive or, in some cases, a combination of all three!
In order to overcome these problems, we have decided to produce these items ourselves. All items will be branded under our 'ROO BITS label. The first parts are now in stock.

740KMG : 40-1 ratio gears for 7mm scale or larger. Price £16-50 per set.
726KMG : 26-1 ratio gears for 7mm scale or larger. Price £16-50 per set.

Made locally for us by a specialist gear manufacturer, these high-quality gearsets consist of a stainless steel worm to fit a 2mm motor shaft and a brass helical gear to fit a standard 3/16" axle. Both gears are supplied with slotted steel grubscrew fixings for easy fitting. Although intended for use with our own motor mounts, these gears will also fit mounts supplied by a number of other manufacturers, including Connoisseur Models.

Careful design means assembly of the worm to the recommended Mashima 1833 or 1824 can motor (also available from us) will automatically give the correct working clearance from the motor body, allowing easy access to the shaft bearing for lubrication purposes. In addition, the helical gear has been made with the toothed working surface 50% wider than is usual, providing a number of benefits. Not only is wear reduced to a minimum and lubricant retention improved, but sideplay can be allowed on the driven axle to help your model negotiate the tighter-than-prototype curves so many of us have to put up with.

Please note: these gears have been designed and produced to give good slow-speed running and shunting operation on the average indoor model railway. We do not recommend you install them in the large Pacific or heavy freight 2-8-0 you intend to leave tearing round the garden railway hauling ten bogie coaches or fifty wagons for hours on end.
